Security Overview

Extreme Networks products incorporate a number of features designed to enhance the security of your

network. No one feature can insure security, but by using a number of features in concert, you can

substantially improve the security of your network. The features described in this chapter are part of an

overall approach to network security

Network Access Security

Network access security features control devices accessing your network. In this category are the

following features:

• IP Access Lists (ACLs)

IP Access Lists (ACLs)

IP access lists consist of IP access rules and are used to perform packet filtering and forwarding

decisions on incoming traffic. Each packet arriving on an ingress port is compared to the access list

applied to that port and is either permitted or denied. Permitted and denied (dropped) packets can also

be counted. Using access lists has no impact on switch performance.
